Defaults (software)
defaults is a command line utility that manipulates plist files. Introduced in 1998 OPENSTEP, ''defaults'' is found in the system's descendants macOS and GNUstep. The name "defaults" derives from OpenStep's name for user preferences, ''Defaults'', or ''NSUserDefaults'' in Foundation Kit. Each application had its own defaults plist ("domain"), under for the user configuration and for the system configuration. The lookup system also supports a , where defaults written there will be seen by all applications. In macOS, the part of the path is replaced by the more intuitive . ''defaults'' accesses the plists based on the domain given. ''defaults'' is also able to read and write any plist specified with a path, although Apple plans to phase out this utility in a future version. Usage Common uses of defaults: $ defaults read DOMAIN # gets all $ defaults read DOMAIN PROPERTY_NAME # gets $ defaults write DOMAIN PROPERTY_NAME VALUE # sets $ defaults delete DOMAIN PROPERTY_NAM ...

Default (computer Science)
A default, in computer science, refers to the preexisting value of a user-configurable setting that is assigned to a software application, computer program or device. Such settings are also called factory settings, or factory presets, especially for electronic devices. Default values are standards values that are universal to all instances of the device or model and intended to make the device as accessible as possible "out of the box" without necessitating a lengthy configuration process prior to use. The user only has to modify the default settings according to their personal preferences. In many devices, the user has the option to restore these default settings for one or all options. Such an assignment makes the choice of that setting or value more likely, this is called the default effect. Examples Application software preferences One use of default parameters is for initial settings for application software. For example, the first time a user runs an application it may ...

Command-line Interface
A command-line interface (CLI) is a means of interacting with software via command (computing), commands each formatted as a line of text. Command-line interfaces emerged in the mid-1960s, on computer terminals, as an interactive and more user-friendly alternative to the non-interactive mode available with punched cards. For a long time, a CLI was the most common interface for software, but today a graphical user interface (GUI) is more common. Nonetheless, many programs such as operating system and software development utility software, utilities still provide CLI. A CLI enables automation, automating computer program, programs since commands can be stored in a scripting language, script computer file, file that can be used repeatedly. A script allows its contained commands to be executed as group; as a program; as a command. A CLI is made possible by command-line interpreters or command-line processors, which are programs that execute input commands. Alternatives to a CLI ...

Property List
In the macOS, iOS, NeXTSTEP, and GNUstep programming frameworks, property list files are files that store serialized objects. Property list files use the filename extension .plist, and thus are often referred to as p-list files. Property list files are often used to store a user's settings. They are also used to store information about bundles and applications, a task served by the resource fork in the old Mac OS. Property lists are also used for localization strings for development. These files use the .strings or .stringsdict extensions. The former is a "reduced" old-style plist containing only one dictionary without the braces (see ), while the latter is a fully fledged plist. Xcode also uses a .pbxproj extension for old-style plists used as project files. Representations Since the data represented by property lists is somewhat abstract, the underlying file format can be implemented many ways. Namely, NeXTSTEP used one format to represent a property list, and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OPENSTEP
OpenStep is an object-oriented application programming interface (API) specification developed by NeXT. It provides a framework for building graphical user interfaces (GUIs) and developing software applications. OpenStep was designed to be platform-independent, allowing developers to write code that could run on multiple operating systems, including NeXTSTEP, Windows NT, and various Unix-based systems. It has influenced the development of other GUI frameworks, such as Cocoa for macOS, and GNUstep. OpenStep was principally developed by NeXT and Sun Microsystems, to allow advanced application development on Sun's operating systems, specifically Solaris. NeXT produced a version of OpenStep for its own Mach-based Unix OS, stylized in all capital letters as OPENSTEP. The software libraries that shipped with OPENSTEP are a superset of the original OpenStep specification, including many features from the original NeXTSTEP. History Workstations from Sun Microsystems were originally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MacOS
macOS, previously OS X and originally Mac OS X, is a Unix, Unix-based operating system developed and marketed by Apple Inc., Apple since 2001. It is the current operating system for Apple's Mac (computer), Mac computers. Within the market of Desktop computer, desktop and laptop computers, it is the Usage share of operating systems#Desktop and laptop computers, second most widely used desktop OS, after Microsoft Windows and ahead of all Linux distributions, including ChromeOS and SteamOS. , the most recent release of macOS is MacOS Sequoia, macOS 15 Sequoia, the 21st major version of macOS. Mac OS X succeeded classic Mac OS, the primary Mac operating systems, Macintosh operating system from 1984 to 2001. Its underlying architecture came from NeXT's NeXTSTEP, as a result of NeXT#1997–2006: Acquisition by Apple, Apple's acquisition of NeXT, which also brought Steve Jobs back to Apple. The first desktop version, Mac OS X 10.0, was released on March 24, 2001. Mac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNUstep
GNUstep is a free software implementation of the Cocoa (formerly OpenStep) Objective-C frameworks, widget toolkit, and application development tools for Unix-like operating systems and Microsoft Windows. It is part of the GNU Project. GNUstep features a cross-platform, object-oriented IDE. Apart from the default Objective-C interface, GNUstep also has bindings for Java, Ruby, GNU Guile and Scheme. The GNUstep developers track some additions to Apple's Cocoa to remain compatible. The roots of the GNUstep application interface are the same as the roots of Cocoa: NeXTSTEP and OpenStep. GNUstep thus predates Cocoa, which emerged when Apple acquired NeXT's technology and incorporated it into the development of the original Mac OS X, while GNUstep was initially an effort by GNU developers to replicate the technically ambitious NeXTSTEP's programmer-friendly features. History GNUstep began when Paul Kunz and others at Stanford Linear Accelerator Center wanted to port Hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Configuration
In communications or computer systems, a configuration of a system refers to the arrangement of each of its functional units, according to their nature, number and chief characteristics. Often, configuration pertains to the choice of hardware, software, firmware, and documentation. Along with its architecture, the configuration of a computer system affects both its function and performance. The configuration of a computer is typically recorded in a configuration file. In modern computer systems, this is created and updated automatically as physical components are added or removed. Applications may assume that the configuration file is an accurate representation of the physical configuration and act accordingly. Most modern computer systems provide a mechanism called the system settings (or "control panel") that permits users to set their preferences. These include system accessibility options (such as the default size of the system font), brightness and contrast; security ...

Foundation Kit
The Foundation Kit, or just Foundation for short, is an Objective-C framework in the OpenStep specification described by NeXT Computer, Inc.. It provides basic classes such as wrapper classes and data structure classes. This framework uses the prefix NS (for NeXTSTEP). It is also part of Cocoa and of the Swift standard library. Classes NSObject This class is the most common base class for Objective-C hierarchies and provides standard methods for working with objects by managing the memory associated with them and querying them. NSString and NSMutableString A class used for string manipulation, representing a Unicode string (most typically using UTF-16 as its internal format). NSString is immutable, and thus can only be initialized but not modified. NSMutableString is a modifiable version. NSValue and NSNumber NSValue is a wrapper class for C data types, and NSNumber is a wrapper class for C number data types such as int, double, and float. The data structures in Foun ...

Home Directory
A home directory is a directory (file systems), file system directory on a multi-user operating system containing computer file, files for a given user (computing), user of the system. The specifics of the home directory (such as its name and location) are defined by the operating system involved; for example, Linux / BSD (Filesystem Hierarchy Standard, FHS) systems use /home/ or /usr/home/, macOS uses /Users/, and Microsoft Windows, Windows systems since Windows Vista use \Users\. Description A user's home directory is intended to contain that user's files; including text documents, music, pictures, videos, etc. It may also include their configuration files of preferred settings for any software they have used there and might have tailored to their liking: web browser bookmark (digital), bookmarks, favorite desktop metaphor, desktop wallpaper (computing), wallpaper and theme (computing), themes, stored passwords to any external services accessed via a given software, etc. The use ...

Root Directory
In a Computing, computer file system, and primarily used in the Unix and Unix-like operating systems, the root directory is the first or top-most Directory (computing), directory in a hierarchy. It can be likened to the trunk of a Tree (data structure), tree, as the starting point where all branches originate from. The root file system is the file system contained on the same Disk Partition Recovery, disk partition on which the root directory is located; it is the filesystem on top of which all other file systems are Mount (computing), mounted as the system boots up. Unix-like systems Unix abstracts the nature of this tree hierarchy entirely and in Unix and Unix-like systems the root directory is denoted by the / (slash) sign. Though the root directory is conventionally referred to as /, the directory entry itself has no name its path is the "empty" part before the initial directory separator character (/). All file system entries, including mounted file systems are "branches" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reverse Domain Name Notation
Reverse domain name notation (or reverse-DNS) is a naming convention for components, packages, types or file names used by a programming language, system or framework. Reverse-DNS strings are based on registered domain names, with the order of the components reversed for grouping purposes. For example, if a company making the product "MyProduct" has the domain name example.com, they could use the reverse-DNS string com.example.MyProduct as an identifier for that product. Reverse-DNS names are a simple way of eliminating namespace collisions, since any registered domain name is globally unique to its owner (with alt roots making exceptions to this rule possible but unlikely). History The first appearance of reversed DNS strings predated the Internet domain name standards. The UK Joint Academic Networking Team (JANET) used this order in its Name Registration Scheme, before the Internet domain name standard was established. For example, the name uk.ac.bris.pys.as was interprete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safari (web Browser)
Safari is a web browser developed by Apple Inc., Apple. It is built into several of List of Apple operating systems, Apple's operating systems, including macOS, iOS, iPadOS, and visionOS, and uses Apple's open-source software, open-source browser engine WebKit, which was Program derivation, derived from KHTML. Safari was introduced in Mac OS X Panther in January 2003. It has been included with the iPhone since the first-generation iPhone in 2007. At that time, Safari was the fastest browser on the Mac (computer), Mac. Between 2007 and 2012, Apple maintained a Microsoft Windows, Windows version, but abandoned it due to low market share. In 2010, Safari 5 introduced a reader mode, Browser extension, extensions, and developer tools. Safari 11, released in 2017, added Intelligent Tracking Prevention, which uses artificial intelligence to block web tracking. Safari 13 added support for Apple Pay, and authentication with FIDO2 Project, FIDO2 security keys. Its interface was redesign ...
